This thesis entitled, “Supplementary Materials in Philippine Politics and Governance.” Intended to find out answers to the following questions: 1. What is the level of validation of the Supplementary materials in Philippine Politics and Governance described in terms of parts as: objectives content activities and evaluation? 2. What is the level of Validity of Supplementary materials in Philippine Politics and Governance described in terms of characteristics to: suitability usability and consistency? 3. What is the mean performance of the students in terms of pretest, post-test? 4. What is the mean performance of the student in terms of performance task? 5. Is there any significant difference in the mean performance of the students in terms of pretest and post-test? and 6. Do Supplementary materials in Philippine Politics and Governance significantly affect the student performance task? The respondents for this particular research were teachers of Social Science and the student from General Academic Strand (GAS) and Humanities and Social Sciences (HUMSS) in the District of Magdalena. In this study, teachers will choose as a sample among the population of teachers, (10) teachers of Buenavista Integrated National High School, Cigaras, Magdalena, and (10) teachers of Magdalena Integrated National High School Magdalena, Laguna, with the total of twenty (20) teachers in District of Magdalena, and (50) students from HUMSS and (25) students from GAS, with a total of 75 students in the District of Magdalena. The level of validation for the supplementary materials in Philippine Politics and Governance received very high ratings from the respondents. This includes the objectives, content, activities, and evaluation. Additionally, the standard deviations were reported for each variable. The supplementary materials in Philippine Politics and Governance were deemed highly valid by the respondents in terms of their suitability, usability, and consistency. The ratings for each variable were reported as very high, along with their respective standard deviations. The pretest and post-test performance of 75 respondents showed that the highest frequency of pre-test scores fell within the range of 21-30, while the highest frequency of post-test scores fell within the range of 31 to 40. The mean and standard deviation for the pre-test score were reported as satisfactory, while the post-test score showed an improvement rated as very satisfactory. Out of 75 respondents, all of the respondents score range from “85 to 89” on practical task 1 and 2 and from “90 to 100” on practical task 3 and 4 received the highest frequency of seventy-five (75) or 100.00% of the total sample population. The mean and standard deviation for the practical task remarked as Outstanding improved based on the score. The pre-test and post-test showed a significant difference in the performance of the students after the use of the supplementary materials, as indicated by the computed t values which were greater than the critical t value. Additionally, the p-values obtained were less than the significance alpha 0.05, suggesting the presence of a significance. The supplementary materials have a significant effect on the students practical task performance which are all statistically significant. The beta coefficient indicates the strength and direction of the relationship between the supplementary materials and practical task performance, with a positive coefficient suggesting that the supplementary materials improve performance. The computed t values obtained from the practical task which were greater than the critical t value. Furthermore, the p-values obtained were less than the significance alpha 0.05, hence there is presence of a significance. From the findings above, we can infer that at 0.05 level of significance, the null hypothesis “There is no significant difference in the performance of the students in terms of pre-test and post-test” and “There is no significant effect on the supplementary materials in Philippine Politics and Governance in terms of performance task” is rejected. Results indicate that using supplementary materials had a significant impact on students performance, as demonstrated by the significant difference between the pre-test and post-test scores. This suggests that the supplementary materials were effective in improving the students understanding of the subject matter.
